Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed May 16,1906. Serial No. 817,196.

vented certain new and useful Improvements in Looks for IncandescentLamps, of

which the following is a specification, refer,

ence being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in.globe-holders; and

the invention aims to provide a novel form oflock for holding a" globeinengagement with its socket,- whereby the same cannot be stolen orfraudulently removed from its 1 socket. 'To this end I have devised asimple and inexpensive .globeeholder which can be easily and quicklyplaced in engagement.

with a globe and'loc'ked in engagement with the socket of said globe,whereby the globe cannot'be removed until the holder =has been detachedfrom the socket, and in this connection the holder is particularlyvsulapted for -incandescentalightv .,globes,=.= -whichoften stolen fromtheir sockets and used in connection with other sockets.

in constructing my improved holder Iaini.

to prowixle ws'iti-veand' reliable sneans for embracing anincandescent-light bulb and retaining it within its socket, said meansin in the claims, and referring to the drawings accompanying thisapplication like numerals of reference designate corresponding partsthroughout the several views, in which Figure 1 is a side elevation ofmy improved globe-holder. Fig. 2 is a front elevation of the same. Fig.3 is a plan of a cap used in connection with the holder. Fig. 4 is adetail sectional view of the same. Fig. 5 is a detail sectional view ofthe retaining band or ring used in connection with the holder. Fig. 6 isa detail sectional view of a portion of the holder. Fig. 7 is aperspective view of the retaining band or ring.

In the accompanying drawings, I have illustrated a conventional form ofelectricbulb socket 1 as containing a bulb or globe 2, said bulb orglobe having a conventional form of nipple 3 at its large end.

My invention resides in providing the end of the socket 1 with a cap4,1saidca being provided with a central opening 5 an with a split 6, thesplit edges of said cap being rovided withupwardly-extending ierced 7 7,whereby a seal 8 or a similar ock may be placed in engagement with thepierced lugs 7 to lock the cap 4 upon the socket 1. The cap is providedwith diametrically opposed openings 9 :9, and in said openings aremounted the ends 10 10 of a piece of wire 11, said wire extending aroundthe large end of the bulb or globe 2 to retaiinsaidbulb or globe withinthe socket 1.

To prevent the wire 1 1 from being removed from the globe orbulb 2, thewire intermedi ate'its endsis flattened, as at 12, and provided witlianopening 14 to receive the'nipple .3 upon the rear end of the bulb orglobe 2. A retaining band or ring-15 is also employed .ugs,

in connection with theglobe or bulb 2, this 1 band or ring being slippedupon the end of the-globe-or bulb prior to its insertion Within v.thesocket 1.. The band or ring 15 is split, as -qat 11.6, -to..'if'crm -ad7i 11fldel"W-liil(h .athe wire 11 upon eachside or 'the bulbisadaptedto pass. After-the holder has been placed in engagement with the bulb orglobe 2 and the socket 1 the cap 4 canbe easily and iiickly placedoverthe: end of the socket and ocked thereon, whereby the-bulb or globe-,2cannot be surre titiously removed from the socket 1 The obe or bulbholder is preferably constructed of light and durable metal and of anon-fusible wire, which in no manner whatever will shield the lightradiating from the bulb or globe 2 when the same is being used.

Such changes in the construction of my improved globe as are permissibleby the appended claims may be resorted to without departing from thespirit andscope of the invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a lock for incandescent lamps, the combination with a lamp-socketand a lamp bulb or globe in said socket, of a split cap mounted on thesocket, a wire passed around the globe or bulb lengthwise thereof andhaving its ends fastened to the cap, and a retaining-ring carried bysaid wire and surrounding the upper end of the bulb or globe,substantially as described.

2. In a lock for incandescent lamps, the

' combination with a lamp-socket, and a bulb "bait or gkme pieced inengagement the or globe carried thereby, of a split cap'fitted on theupper end of the socket, pierced lugs'l carried'by said cap, a lock eaging said pierced lugs, a wire carried by iiiecap and extending aroundthe bulbior globe len th- I 5 Wise thereof, and a retainin -ring carrieby the wire and surrounding tie upper end of the bulb or globe.

In testimony whereof I affix my signature in'the presenceof twowitnesses.
